Intel Arcを解説するLisa Pearce氏 (Vice President and General Manager, Visual Compute Group Intel Accelerated Computing Systems and Graphics Group)
Mi IntelFrom the 27th to the 28th is organizing a private event “Intel Innovation”. The main event was the announcement of the 12th generation Core, but in the main video, there was an explanation of the tasks related to the next discrete GPU “Ark” (codename: Alchemist).
The Arc is manufactured by TSMC’s 6nm process, and the top model has 32 built-in Xe cores. It has all the latest features needed to run modern games, supports DirectX 12 Ultimate, and supports hardware ray tracing, mesh shaders, variable shading, and more.
It also has an independent AI acceleration feature, which the company calls “XMX AI Acceleration”. It seems that it is equivalent to the Tensor core in NVIDIA, but as a technology for its use, the high resolution technology “XeSS” was introduced.
Functions of XMX AI Acceleration
The XeSS technology itself is similar in goal to NVIDIA’s DLSS and AMD’s FidelityFX Super Resolution, and games will be rendered at lower resolutions to improve performance by reducing GPU load, while complementing pixels to show higher resolutions. Will be done. However, it has projected multiple frames or higher resolution images in the past, and the approach seems closer to NVIDIA’s DLSS.
This also required XeSS to be supported in-game, but the keynote demonstrated that “The Riftbreaker” runs on Alchemist (beta demo revision 22335) was used. It can be confirmed that a large number of 3D objects play smoothly when captured by XeSS at 4K resolution, which is better than 1080p.
The XESS by XMX AI Acceleration can easily outperform 4K resolution compared to 1080p.
If you double or quadruple, the difference is obvious.
Another feature of the Arc is the “deep link” technology already available in the entry-level Xe MAX. Deep Link uses a GPU’s encoder and a discrete GPU’s encoder with the built-in CPU at the same time to reduce transcoding times, but it is also available in Arch.
In the keynote, it was emphasized that if the video conversion software “Handbrake” is used to perform the format conversion by syncing the XE graphics with a built-in CPU and Arc, the time could be significantly reduced.

Video conversion performance using Handbrake
The conversion work was first completed when the GPU operated in cooperation with the underlying CPU and discrete GPU using Deep Link.
